Lab-grown diamonds: Diamonds created in a laboratory using high pressure and heat. CVD diamonds: A type of lab-grown diamond created using chemical vapour deposition.
The main difference between lab-grown diamonds and CVD diamonds is the way they are created. Lab-grown diamonds are created using high pressure and heat, while CVD diamonds are created using chemical vapor deposition.
High pressure and heat: In the high pressure and heat process, a diamond seed is placed in a chamber and exposed to extreme temperatures and pressures. This causes the carbon atoms to bond together and form a diamond. Chemical vapour deposition: In the chemical vapor deposition process, a diamond seed is placed in a chamber and exposed to a mixture of gases. The gases are heated, and the carbon atoms in the gases bond together to form a diamond.
Both lab-grown diamonds and CVD diamonds are chemically identical to natural diamonds. However, CVD diamonds are typically more expensive than lab-grown diamonds created using other methods.
